Wipers not returning to 'at rest' position correctly - fixed.
I've been having a problem here or there where my wipers were not returning to the proper at-rest position. They were still propping up about an inch or so. Not a huge amount, but enough to bug me.
I took a look at things tonight, and got the problem fixed. I believe the contacts in the cam within the wiper motor were malfunctioning. If you run into this too, these are the steps I took.
1) Remove wipers. Plastic cover pops up and off of them to expose the 13mm nut. Use a screwdriver to pop the wipers off the bosses.
2) Remove cowl - 2 torx screws on each side and 2 tree push-pins on the upper firewall.
3) Remove wiper assembly. 10mm bolts on each side of the wiper arm assembly. Disconnect wiring harness - lift out.
4) Remove three torx screw securing plastic cam-cover.
You'll see it's full of grease. Even at 96k miles, and 4 years, my grease was still nice and clear. I scooped it out and saved. it. I then checked the contacts on the plastic cover. I gave them a slight tweak outward to give them a little more pressure on the cam contacts. I took a shop towel and cleaned the contacts on the cam wheel, and re-applied the grease I saved. I also packed some into the worm gear.
Reassemble in reverse..

Sorry 
I am notoriously bad at slowing down enough to take pics of anything.
I can say for sure, it is VERY easy to perform the steps I mentioned. Everything came apart incredibly easy -- I'm not leaving anything out - No fumbling with nearly impossible to use clips or prying on things for 10 minutes.
Having done it once, I could have the whole wiper assembly out in less than 5 minutes. Jeep did good with this setup.
